Amid renewed Israeli calls for residents of Gaza to evacuate from across the Strip, the UN Agency for Palestine Refugees (UNRWA) says no part of the enclave is safe for residents.

“We have lost more than 130 colleagues, half of them were killed in the central and southern areas,” Juliette Touma, the director of communications at the UNRWA, told Al Jazeera.

“This is just one example that shows that nowhere is safe,” she said.

Touma said UNRWA managed to get some humanitarian aid, including fuel, into Gaza during the recent truce. “We need to go back to that as a minimum,” she said, calling for a humanitarian ceasefire to take place immediately.

She said UNRWA’s centre in Khan Younis, meant to host 1,000 people, was now home to more than 30,000. Touma visited the centre at the beginning of the month and described what she witnessed as “misery galore” and “desperation”.
